Tulowitzki's once-comfortable lead in the voting has shrunk to 244,832 votes -- a margin Reyes, playing in the country's biggest market, might be able to make up before the starting lineups are announced on Sunday.
Tulowitzki, the Rockies' cleanup hitter, has entered Monday as the consistent leader among Major League shortstops this season in home runs (14) and RBIs (50) and is regarded as the games rangiest shortstop. Tulowitzki began the day with a .990 fielding percentage, which also led Major League shortstops.
Reyes, the Mets' leadoff man, began the week leading the NL in batting at .341, and his .385 on-base percentage is tied with the Dogers' Jamey Carroll's for tops among Major League shortstops. Reyes' 37 extra-base hits are tops in baseball, with Tulowitzki and the Indians' Asdrubal Cabrera tied for second at 34.
